Door operating and locking device



the lever may assume a pendant position under the influence of gravity,as clearly shown in dotted lines in Figure l.

The bracket A is in the form of a plate applied to the ydoor stop 13 andthe adj acenl portion of the side wall of the car, being se curedthereto by bolts 2li-2l or any other suitable fastening devices.Thatportion of the plate applied to the door stop is outwardly offsetwith reference to the main body portion of the plate as indicated at 22in Figure 2 andis set into the stop so as to have the outer surfacethereof flush with the outer face of the stop. Along its lo-wer edge theplate is provided with an outstanding horizontally cisposed flange 23extending from the offset portion to the opposite end of the plate, thefront end of the flange being substantially in alinement with the outerface of the door stop and door. The offset portion 22 of the plate isindented to provide a pocket as indicated at 24 adapted to accommodatethe fulcrum member of the lever D# The door stop 13 is correspondinglyrecessed to receive the indented portion of the plate. At the bottom ofthe pocket 24 an outstanding lug 25 is provided having an upwardlyinclined front face 26 on which the fulcrum member l5 of the lever isadapted to ride. At its rear side, the lug has a vertically disposedabutment face behind which the fulcrum member is adapted to engage. Thepocket 24 is also provided with a vertically disposed end wall 27adapted to form an abutment for the fulcrum member. As shown, the lug isspaced from the end wall 27 a suiiicient distance to accommodate thefulcrum member therebetween. Formed integral with the plate is a hood,comprising a longitudinally extending, vertically disposed side wall 28and a longitudinally extending top wall 29. The side wall 28 is spacedoutwardly fiom the outer edge of the flange 23 and t-he outer face ofthe door stop 13 a sufficient distance to permit the lever D to swingtherebetween and a portion thereof is offset as shown in Figure 2 toaccommo date the link C. The lower edge of the wall is preferablybeveled'at the inner side as indicated at 30 to aid in properly guidingthe lever behind the wall. Formed integral with the bottom edge of thewall .28 at the rear end of the hood is a laterally project-ing,horizontally disposed ear 3l provided with an opening for a purposehereinafter described. Adjacent the rear end of the hood, the top wall29 is provided with an opening 32 adapted to receive the lug 17 in oneof the positions of the lever D. l

The latch member E comprises a vertically disposed bearing member 33 anda horizontally disposed arm 34 extending therefrom. The bearing member33 is disposed between the upper wall 29 of the hood and the flange 23having its lower end supported by the lattei'. The bearing member 33 ispivotally mounted to swing about a vertical axis on a bolt 35 extendingtherethrough, through the wall 29 and flange 23. The upper portion ofthe bearing` member 33 is of cylindrical form and bears on the curvedsurface 36 of the wall of a downwardly opening pocket 37 into which itextends. rl`he arm 34 is adapted to be swung into position at rightangles to the side wall of the car and under the ear 3l to support thelever D when in horizontal position, as clearly shown in Figures 2 and4. The fiee end of the arm is provided with an opening 38 which isadapted to register with the opening in the ear 3l when the arm is swunginto position under the ear. The registering openings in the .arm andear are adapted to receive the usual car seal or any other lockingmember in a well known manner. A vertically disposed rib 39 outstandingfrom the plate of the bracket A acts as a limiting stop for the arm toassure registration of the seal receiving openings.

As clearly shown in t-he drawings, when the arm 34 is in the positionjust described,

support-ing the lever 'D,fthe latter is confined within the hood of thebracket A and retained in'position by the walls 28 and 29 thereof, theoffset portion of the plate and the wall of the pocket 36. It will beevident that the fulcrum member l5 is thus prevented from beingdisengaged from behind the lug 25.

The car door is cut away at the outer side adjacent the front edge asindicated at 40 to ffl accommodate the fulcrum member 15 when the leverand link are in the pendant position, and the wear plate G which isapplied to the outer surface of the door and secured thereto by screwsis provided with a similar opening registering with the opening in thedoor,the edges of the plate along the opening therein providing wearsurfaces protecting the walls of the opening 40.

The supporting member F is pivotally mounted on the outer side of thedoor by a bolt 4l extending through the upper end thereof and isprovided with a socket 42 adapted to receive the extremity of the handle14 of the lever to support the lever in an inclined position with thefulcrum member l5 thereof so disposed that it will engage the inclinedface 26 of the lug 25 when the door is moved toward the stop. Theposition of the bolt 4l is such that the center of gravity of thesupport F is disposed to one side of the pivot point thereof when theend of the lever is engaged within the socket 42 so that the supportwill be held in engaging position with the lever under the influence ofgravity.

Assuming that the parts are in the full line position shown in Figure l,the lever being disposed horizontally with the fulcrum member thereofbetween the lug 25 and the abutment Wall 27, When it is desired to openthe door, the follox'viiig sequence of operations are performed. Thelead seal being first broken and removed, the latch member E is swung tothe right, as seen in Figure l, througlranarc of 900, thereby freeingthe lever D from within the pocket defined by the hood. rlhe lever isthen swung ydownwardly in a contra-clockwise direction turning on itsfulcrum member 15 Which at vthis time bears on the Wall 27 and thebottom Wall ofthe pocket 24, forcing the door open through the medium ofthe connecting link C, the lever and the link acting inthe manner of atoggle mechanism. The swinging movement ofthe lever in thedescribed'direction is continued until the desired amount of dooropening is obtained, whereupon the fulcrum ofi` the lever is manuallydisengaged from behind the lug 25 and the lever and link permitted ytodrop to the dotted line position `shown in Figure l.

lVhenit is desi-red to close the door, the latter is moved toa positionas near the stop 13 as can beconveniently `done by the operator Withoutthe use fof tools.` Such a position is indicated in full/lines in.Figure 3. During thetime that thedoor is moved to this position,theleverD may be ysupported by the membenFJasshowm tolproperly guide thefulcrum memher of the lever into engagement with the iiiclined surfaceof the lug 25.' However, it is not necessary `that the leverbe sosupported While pushing the door to the `position shown in Figure 3, butthe same maybeallowedf to hang pendant and then manually engagedr Withthe lug` 25 when the door has rewheely a position shown in Figure 3,Assuming that the lever is supported as shown in Figure 3, Vas thel dooris pushed toward thestop, the fulcrum member 15` will ride the inclinedsurface 26 of the lug 25, finally passing beyondthe same and droppingbehind thelugandfwill be confined between the same the Wall 27 of thepocket 24. To force the'door to closed position, the lever D is swung ina clockwise direction, the support being first disengaged'from .thehandle.` It will be evidenttliat as the leveris swung to a' horizontalposition Within ithe hood of the bracket A, the door will be positivelypulled shut through the medium of the connecting link C, the parts,acting inthe manner of a toggle mechanism as hereinbefore pointed out.To lock the door in position, the latch Eis swunginto en ragenient withthe stopv 39, thereby supportingfthe lever lD'and preventinfrdisengagement of thefulcruin member l5 from betiveenthe lug 25 andtheWall 27. The usual seal'is then applied through the alined openings ofthe arm 34; and ear To lock the door in the partly opened position asshown in Figure 3, the lever D and link C are raised to the dotted lineposition and the lug'17 of the lever engaged Within the recess 3.2 inthe upper Wall of thel hoodof the bracket. The latch E theny swung intoposition to aline the open ing thereof with the opening of the ear andthe usua-lcar seal applied. It will be evident that the arm 34 of thelatch E supports the lever D Whenin the` dotted line amount of force isapplied during the closing and initial openingmovenient ofthe 1 door.
